    I am still in the research process for this project, but I can say how impressed I am with Water…read moreHeaters Masters. They responded to my request so fast I thought it was a bot, but it wasn't. A real person called and left a message. I called back to explain what I was interested in and he scheduled an appointment for that day (I think). I was assured that I'd be called or texted when the technician was on his way. I expected to have to wait the full 2-hour window I was given, but no! I was called about 5 minutes before the window started to see if I was still available. The technician arrived exactly on time, right at the start of the window! After a short explanation of my needs he just said "OK, let's take a look at the space and talk about it." He explained every step of what they'd do to install a tankless water heater, he looked at the whole area to check for pipes, electrical access, spacing inside and out for a condensation line - making feel very comfortable that it would be planned before the installation to avoid last minute issues. A big plus, he told me he'd be part of the installation team. He also told me I should go ahead and get another few quotes. I think these guys are confident they're giving the prices in the sweet spot of costs. Then we spent time just talking about landscaping and plants! I'm not in a hurry to start this project, it's on my list of improvements and I'm just starting to investigate. However, I'm extremely impressed with the service given at this stage, the thorough approach in explaining, and the honestly. I will get another quote, but the next one has a high bar to cross; not only the service, but Water Heaters Masters quote was WELL below the only other quote I had gotten so far. I have a very good feeling about WHM. I'll come back to let you know more when I've finished the whole project.

    After getting a very high quote from a major plumbing chain, we decided to contact Water Heater…read moreMasters. We had an absolutely fantastic experience with Water Heater Masters. Alex sent our technician, Rojo, who helped install a new 40-gallon gas water heater in our indoor utility closet, and he was incredibly diligent, professional, and efficient from start to finish. Installing a tank in an inside closet can be tricky, but Rojo handled the entire job seamlessly in just 2 hours. He replaced everything with high-quality components, including: * New hot and cold water flex lines * A brand new water shut-off valve * A new gas flex line and sediment trap * Fully reworked earthquake straps (to meet California safety codes) * Properly updated T&P line and venting He also took care of the removal and disposal of our heavy 18 yr old tank, leaving the utility closet completely clean. If you want fair pricing, expert specialized service, and a technician who respects your time and home, call Water Heater Masters and ask for Rojo. Highly recommended!

Jeff quickly diagnosed the issue and cleared the drain. It turned out to be a hairball clogging the pipe. Unfortunately, I can't blame my husband for this one since he's bald.

Not exactly the kind of problem you want to deal with, but their team made it so much easier. From the moment I called, Alexis in the front office was wonderful. Friendly, responsive, and on top of everything. She got someone out quickly and kept me updated, which I really appreciated. Adam came to the house, and he was fantastic. Professional, calm, and clearly really knowledgeable. He walked me through what he was seeing, explained the issue without any pressure or upselling, and fixed everything efficiently. You could tell he genuinely cared about doing the job right. It's rare to feel this taken care of by a service company, but Letts Plumbing absolutely delivered. I wouldn't hesitate to call them again and highly recommend them to anyone who needs plumbing help. I'm a licensed contractor, so I have exceptionally high standards and I don't hand out praise lightly. They earned every bit of this review, and I wouldn't hesitate to call them again.

He QUICKLY said that they could absolutely do the job for $2,500! I told Beto I was concerned that he was just quoting my deductible, and he said that he understood and he could do the job for $2,000. but he had to call in a smaller employee in case they had to go into crawl space and dig (the crawl space is very tight). I asked him what if leak was against the wall and no digging was needed, he assured me price would be adjusted accordingly. again, my fault for not getting this in writing. He attempted to get to leak from garage and was unable to, so had to cut into my family room floor and wall. As I guessed leak was against the wall and was repaired. No one needed to go under house. Beto called two other workers (according to him because they had a small stature in case crawling was needed). I never saw all three working, two basically hung out. At the end I was presented with the $2,000 bill, I asked about the adjustment since no digging was needed, Beto told me his boss said no. but he would be nice and deduct $100. I paid my bill and called the owner with my concerns-he said that a quote should never be given before the plumber could see the actual problem and he would talk to Beto and call me back. That was last week, no call back. I waited to write this review to see if the owner would make things right, or at least explain the charges. So beware of this company-or at least Beto and his quotes, don't make my mistake and agree under stress and pressure! I had an active hot water leak under my house and I should have known better, but I didn't and they took advantage.
